- Background - white or white-on-white
- Scraps - bright solids or tone-on-tone prints (avoid prints with too many colours)
Cut an 8-1/2 inch square from your background fabric. For the bright scraps I used strips that were about 5 inches long and between 1 and 2-1/2 inches wide but you can use smaller ones that are 2-1/2 inches long (more about this later).
Sew the scraps together. In my case I made one strip that was more than 14 inches long and 5 inches wide. If you use smaller scraps you will need to make 2 strips, each about 2-1/2 inches wide and at least 14 inches long. These are bigger than they need to be but will be trimmed down.
Press well and then trim the stip down so that you have 2 strips that are 2 inches wide and 14 inches long. For mine I made one strip and then cut it lengthwise to make 2 strips.
Cut your white background square in half along the diagonal.
Sew one strip along the diagonal of one of the white triangles. Make sure you center the strip - it will stick out quite a bit at each end. Also be careful on the bias of the white triangle - try not to stretch it while you sew.
Press the seam towards the white. Lay the other half of the triangle on top so that the points are lined up. Sew this together watching out for that stretchy bias edge.
Press well. You should now have a square with the scrappy strip in the middle. Leave the ends untrimmed and sticking out.
Cut the square again on the diagonal perpendicular to the scrappy strip.
Using the same method as before, sew the strip to one triangle, press, and then line up the other triangle and sew it on.
Press well and then trim the square down to 9-1/2 inches. Make sure when you trim that you keep the X centered. I used a 6 inch wide ruler and lined up 4-3/4 inches on the inner corners of the X to center it. You're done!
